ENVIRONMENTAL PROTECTION AGENCY
[EPA-HQ-OAR-2007-1196; FRL-9781-1]
Recent Postings of Broadly Applicable Alternative Test Methods
AGENCY: Environmental Protection Agency (EPA).
ACTION: Notice of availability.
-----------------------------------------------------------------------
SUMMARY: This notice announces the broadly applicable alternative test
method approval decisions the EPA has made under and in support of New
Source Performance Standards (NSPS) and the National Emission Standards
for Hazardous Air Pollutants (NESHAP) under the Clean Air Act (CAA) in
2012.
FOR FURTHER INFORMATION CONTACT: An electronic copy of each alternative
test method approval document is available on the EPA's Web site at
www.epa.gov/ttn/emc/approalt.html. For questions about this notice,
contact Ms. Lula H. Melton, Air Quality Assessment Division, Office of
Air Quality Planning and Standards (E143-02), Environmental Protection
Agency, Research Triangle Park, NC 27711; telephone number: 919-541-
2910; fax number: 919-541-0516; email address: melton.lula@epa.gov. For
technical questions about individual alternative test method decisions,
refer to the contact person identified in the individual approval
documents.
SUPPLEMENTARY INFORMATION:
I. General Information
A. Does this notice apply to me?
This notice will be of interest to entities regulated under 40 Code
of Federal Regulations (CFR) parts 60, 61, and 63, state, local, and
tribal agencies, and the EPA Regional Offices responsible for
implementation and enforcement of regulations under 40 CFR parts 60,
61, and 63.
B. How can I get copies of this information?
You may access copies of the broadly applicable alternative test
method approval documents from the EPA's Web site at www.epa.gov/ttn/emc/approalt.html.
II. Background
Broadly applicable alternative test method approval decisions made
by the EPA in 2012 under the NSPS, 40 CFR part 60 and the NESHAP, and
40 CFR parts 61 and 63 are identified in this notice (see Table 1).
Source owners and operators may voluntarily use these broadly
applicable alternative test methods subject to their specific
applicability. Use of these broadly applicable alternative test methods
does not change the applicable emission standards.
As explained in a previous Federal Register notice published at 72
FR 4257 (January 30, 2007) and found on the EPA's Web site at
www.epa.gov/ttn/emc/approalt.html, the EPA Administrator has the
authority to approve the use of alternative test methods to comply with
requirements under 40 CFR parts 60, 61, and 63. This authority is found
in sections 60.8(b)(3), 61.13(h)(1)(ii), and 63.7(e)(2)(ii). In the
past, we have performed thorough technical reviews of numerous requests
for alternatives and modifications to test methods and procedures.
Based on these reviews, we have often found that these changes or
alternatives would be equally valid and appropriate to apply to other
sources within a particular class, category, or subcategory.
Consequently, we have concluded that, where a method modification or an
alternative method is clearly broadly applicable to a class, category,
or subcategory of sources, it is both more equitable and efficient to
approve its use for all appropriate sources and situations at the same
time.
It is important to clarify that alternative methods are not
mandatory but permissive. Sources are not required to employ such a
method but may choose to do so in appropriate cases. Source owners or
operators should review the specific broadly applicable alternative
method approval decision on the EPA's Web site at www.epa.gov/ttn/emc/approalt.html before electing to employ it. As per 63.7(f)(5), by
electing to use an alternative method for 40 CFR part 63 standards, the
source owner or operator must continue to use the alternative method
until approved otherwise.
The criteria for approval and procedures for submission and review
of broadly applicable alternative test methods are outlined at 72 FR
4257 (January 30, 2007). We will continue to announce approvals for
broadly applicable alternative test methods on the EPA's Web site at
www.epa.gov/ttn/emc/approalt.html and annually publish a notice that
summarizes approvals for broadly applicable alternative test methods.
This notice comprises a summary of seven such approval documents
added to our Technology Transfer Network from January 1, 2012, through
December 31, 2012. The alternative method decision letter/memo number,
the reference method affected, sources allowed to use this alternative,
and the modification or alternative method allowed are summarized in
Table 1 of this notice. Please refer to the complete copies of these
approval documents available from the EPA's Web site at www.epa.gov/ttn/emc/approalt.html as Table 1 serves only as a brief summary of the
broadly applicable alternative test methods. In addition to alternative
decisions listed in Table 1, we received comments and updated
Alternative-082, which was approved the previous year in 2011. This
alternative approval letter can also be viewed at www.epa.gov/ttn/emc/approalt.html.
If you are aware of reasons why a particular alternative test
method approval that we issued should not be broadly applicable, we
request that you make us aware of the reasons in writing, and we will
revisit the broad approval. Any objection to a broadly applicable
alternative test method, as well as the resolution of that objection,
will be announced on the EPA's Web site at www.epa.gov/ttn/emc/approalt.html and in the subsequent Federal Register notice. If we
decide to retract a broadly applicable test method, we would continue
to grant case-by-case approvals, as appropriate, and would (as
[[Page 11175]]
states, local and tribal agencies and the EPA Regional Offices should)
consider the need for an appropriate transition period for users either
to request case-by-case approval or to transition to an approved
method.

Acting Director, Office of Air Quality Planning and Standards.
